Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your normal skin due to salicylic acid, which helps to decongest pores and refine texture, but it lacks specialized ingredients to address your main goal of pigmentation.
- While the formula is generally suitable for normal skin, the presence of decyl glucoside and cocamidopropyl betaine provides effective cleansing without sufficient humectant ingredients for optimal hydration.
- The product is safe for your normal skin as it contains no harsh or prohibited ingredients that would cause irritation.
How to apply
- You can use this cleanser AM and PM every single day. Start slowly 3 times a week and move to daily use if your skin likes it.
- Apply this cleanser as the first step in your morning routine or the second step in your evening routine. Follow it with toner and moisturizer.
- Massage a small amount of cleanser gently onto your face using circular motions. Rinse well with lukewarm water and pat dry.
- For the best results, apply your cleanser directly to wet skin to help wash away dirt. Make sure your face is clean before you begin.
- Avoid getting the cleanser in your eyes. Always do a quick patch test before using the product for the very first time.

Questions and answers
How well does Principia GL-01 work for skin with dark spots?
Principia Gel de Limpeza GL-01 works moderately for skin with dark spots because salicylic acid offers light exfoliation and clears pores, but the formula lacks specialized brightening ingredients. A cleanser for this skin needs high-quality ingredients like niacinamide and ceramides alongside a balanced mix of hydrating and soothing components to properly address pigmentation.
Which ingredients make this cleanser a good fit for skin with dark spots?
Salicylic acid helps to decongest pores and refine texture, but this cleanser lacks specialized ingredients to address dark spots. A cleanser for this skin needs high-quality ingredients like niacinamide and ceramides alongside a balanced combination of hydrating and soothing components that improve dark spots without causing irritation.
What does Salicylic Acid do for skin with dark spots?
Salicylic acid helps fade dark spots and uneven skin tone left behind after breakouts. It gently clears away surface buildup, which may improve the look of dark marks and support a smoother, more even complexion over time.
What does Glycerin do for skin with dark spots?
Glycerin helps keep dry skin hydrated and supports a healthy skin barrier, which makes skin feel soft and smooth. While it does not directly fade dark spots on its own, it is often added to spot-fading products to keep the skin comfortable while other ingredients work.

Where does this cleanser go in a skincare routine for skin with dark spots?
This cleanser works as a first step in both morning and evening routines for skin with dark spots, helping to clear pores with salicylic acid. Because it lacks specialized brightening ingredients, a routine for this skin also needs targeted spot-fading treatments and hydrators.
Can I use this cleanser with retinol, and in what order?
How often should I use this cleanser?
You can use this cleanser daily as part of your morning and evening routine, since it gently cleans your skin without causing irritation. Because it works for dark spots only by smoothing texture rather than fading marks, this skin needs a cleanser that adds targeted brightening ingredients and extra moisture.
Can this cleanser clog pores, cause breakouts or purging for skin with dark spots?
This cleanser is unlikely to clog pores or cause breakouts because it contains salicylic acid, which helps to keep pores clear and refine skin texture. However, since it lacks specialized ingredients for dark spots, this skin type needs a cleanser that also includes targeted brightening ingredients.
BioMed Research International, 2020Journal of Cosmetic Dermatology, 2024
Can I use this cleanser around the eyes or on my body?
This cleanser is safe for use on the body, but avoid applying it on the thin skin around the eyes. Products intended for dark spots and body use need specialized brightening ingredients and deep hydration to properly care for those areas.
Is this cleanser fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
What the research says
A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase.
BioMed Research International, 2020Twice daily application of a multitargeted dermocosmetic cream provided comparable efficacy to benzoyl peroxide 5% gel in reducing inflammatory, non-inflammatory, and total lesions in 150 Caucasian subjects with mild-to-moderate acne over 56 days, while demonstrating superior skin tolerability.
Journal of Cosmetic Dermatology, 2024The use of a salicylic acid-based dermocosmetic significantly reduces the needed quantity of benzoyl peroxide without impacting efficacy in mild to moderate acne, and as maintenance post-benzoyl peroxide allows a significant reduction of acne relapse compared to vehicle.
Journal of Drugs in Dermatology, 2023Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients.
CMAJ, 2010Treatment with 2% supramolecular salicylic acid hydrogel resulted in a regression and markedly improvement rate of 51.01% compared to 43.10% for Adapaline gel in patients with mild to moderate facial acne vulgaris, showing no significant difference in efficacy.
Journal of Cosmetic Dermatology, 2024Topical 5% benzoyl peroxide plus salicylic acid achieved the greatest lesion reduction at early 2 to 4 week time points compared to benzoyl peroxide, clindamycin, and combination benzoyl peroxide/clindamycin, while 5% benzoyl peroxide plus salicylic acid and combination benzoyl peroxide/clindamycin showed similar efficacy at 10 to 12 weeks in acne patients.
Journal of the American Academy of Dermatology, 2010A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.
Clinical, Cosmetic and Investigational Dermatology, 2017The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.
Journal of Cosmetic Dermatology, 2020Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.
International Journal of Cosmetic Science, 2001The cytotoxic effect of sodium lauryl sulphate on normal human keratinocytes was significantly decreased when combined with cocamidopropyl betaine, Tween 20, and Tween 80 at concentrations well below the critical micelle concentration.
Skin Pharmacology and Applied Skin Physiology, 2003Coadministration of 40% topical L-menthol with 10% trans-cinnamaldehyde reduced spontaneous pain intensity, neurogenic inflammation, primary and secondary mechanical hyperalgesia, and heat hyperalgesia, but not cold hyperalgesia, in 14 healthy volunteers.
The Journal of Pain, 2016Topical application of menthol-based cooling gel decreased intramuscular temperature by 1.9 °C and increased cutaneous blood flow by 0.3 ml/min in healthy males compared to placebo gel.
International Journal of Sports Physical Therapy, 2018Cooling skin temperature or applying topical menthol reduced histamine-induced itch intensity and flare diameters in healthy male volunteers.

Why other cleansers fit skin with dark spots better
Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.
